●Assisting the driver to judge proper  
following distance 
The dynamic radar cruise control  determines whether the following dis- 
tance between the driver’s own vehi-
cle and a designated vehicle traveling  ahead is within a set range. It is not  
capable of making any other type of 
judgement. Therefore, it is absolutely 
necessary for the driver to remain vig- ilant and to determine whether or not  
there is a possibility of danger in any 
given situation.
●Assisting the driver to operate the 
vehicle 
The dynamic radar cruise control  
does not include functions which will 
prevent or avoid collisions with vehi- cles ahead of your vehicle. Therefore,  
if there is ever any possibility of dan-
ger, the driver must take immediate  and direct control of the vehicle and  
act appropriately in order to ensure 
the safety of all involved.
■Situations unsuitable for 
dynamic radar cruise control 
Do not use dynamic radar cruise con- 
trol in any of the following situations. 
Doing so may result in inappropriate  speed control and could cause an  
accident resulting in death or serious 
injury.

Turning the Blind Spot Monitor on/off.
Outside rear view mirror indica- 
tors
When a vehicle is detected in a blind  
spot of the outside rear view mirrors or 
approaching rapidly from behind into a 
blind spot, the outside rear view mirror 
indicator on the detected side will illumi-
nate. If the turn signal lever is operated 
toward the detected side, the outside 
rear view mirror indicator flashes.
BSM indicator
Illuminates when the Blind Spot Monitor 
is enabled
■Outside rear view mirror indicator  visibility 
In strong sunlight, the outside rear view  
mirror indicator may be  difficult to see.
■When “Blind Spot Monitor Unavail- able” is shown on the multi-infor- 
mation display 
Ice, snow, mud, etc., may be attached to  the rear bumper around the sensors.  
( P.300) The system should return to  
normal operation after removing the ice, 
snow, mud, etc. from the rear bumper.  Additionally, the sensors may not oper- 
ate normally when driving in extremely 
hot or cold environments.
BSM (Blind Spot Moni- 
tor)*
The Blind Spot Monitor is a  
system that uses rear side 
radar sensors installed on the 
inner side of the rear bumper 
on the left and right side to 
assist the driver in confirming 
safety when changing lanes.
WA R N I N G
■Cautions regarding the use of  the system 
The driver is solely responsible for  
safe driving. Always drive safely, tak- ing care to observe your  
surroundings. 
The Blind Spot Monitor is a supple- 
mentary function which alerts the 
driver that a vehicle is in a blind spot  of the outside rear view mirrors or is  
approaching rapidly from behind into 
a blind spot. Do not overly rely on the  Blind Spot Monitor. As the function  
cannot judge if it is safe to change 
lanes, over reliance could lead to an  accident resulting in death or serious  
injury. 
As the system may not function cor- 
rectly under certain conditions, the 
driver’s own visual confirmation of  safety is necessary.

vehicle cannot be detected.
*2: The greater the difference in speed between your vehicle and the detected vehi- 
cle is, the farther away the vehicle will be detected, causing the outside rear view 
mirror indicator to illuminate or flash.
■The Blind Spot Monitor is opera- 
tional when 
The Blind Spot Monitor is operational  
when all of the following conditions are 
met:
●The Blind Spot Monitor is on.
●The shift lever is in a position other 
than R.
●The vehicle speed is greater than 
approximately 16 km/h (10 mph).
■The Blind Spot Monitor will detect a 
vehicle when 
The Blind Spot Monitor will detect a  
vehicle present in the detection area in 
the following situations:
●A vehicle in an adjacent lane over-
takes your vehicle.
●You overtake a vehicle in adjacent 
lane slowly.
●Another vehicle enters the detection 
area when it changes lanes.
■Conditions under which the system  will not detect a vehicle 
The Blind Spot Monitor is not designed  
to detect the following types of vehicles 
and/or objects:
●Small motorcycles, bicycles, pedestri- 
ans, etc.*
●Vehicles traveling in the opposite  
direction
●Guardrails, walls, signs, parked vehi- 
cles and similar stationary objects*
●Following vehicles that are in the  
same lane*
●Vehicles traveling 2 lanes away from 
your vehicle*
●Vehicles which are being overtaken  
rapidly by your vehicle* 
*: Depending on the conditions, detec- 
tion of a vehicle and/or object may 
occur.
■Conditions under which the system  may not function correctly
●The Blind Spot Monitor may not detect vehicles correctly in the following situ- 
ations:
• When the sensor is misaligned due to  a strong impact to the sensor or its  
surrounding area
• When mud, snow, ice, a sticker, etc. is  covering the sensor or surrounding  
area on the rear bumper
• When driving on a road surface that is  wet with standing water during bad  
weather, such as heavy rain, snow, or 
fog • When multiple vehicles are approach- 
ing with only a small gap between 
each vehicle • When the distance between your vehi- 
cle and a following vehicle is short
• When there is a significant difference  in speed between your vehicle and  
the vehicle that enters the detection 
area • When the difference in speed  
between your vehicle and another 
vehicle is changing • When a vehicle enters a detection  
area traveling at about the same 
speed as your vehicle • As your vehicle starts from a stop, a  
vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips  in the road, etc. 
• When driving on roads with sharp 
bends, consecutive curves, or uneven  surfaces 
• When vehicle lanes are wide, or when 
driving on the edge of a lane, and the  vehicle in an adjacent lane is far away  
from your vehicle
• When towing a trailer

attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that 
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of  your vehicle 
People may not be detected if they are  
wearing certain types of clothing.
■Situations in which the system may  not operate properly 
Certain vehicle conditions and the sur- 
rounding environment may affect the  ability of a sensor to correctly detect  
objects. Particular instances where this 
may occur are listed below.
●There is dirt, snow or ice on a sensor. 
(Cleaning the sensors will resolve this  problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)  
In especially cold weather, if a sensor 
is frozen the sensor display may be  displayed abnormally, or objects, such  
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a  sensor is extremely hot or cold.
●On an extremely bumpy road, on an  
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of  large vehicles, the clearance sonar of  
other vehicles or other devices which 
produce ultrasonic waves are near the  
vehicle
●A sensor is coated with a sheet of  
spray or heavy rain.
●If objects draw too close to the sensor.
●When a pedestrian is wearing clothing  that does not reflect ultrasonic waves  
(ex. skirts with ga thers or frills).
●When objects that are not perpendicu- 
lar to the ground, not perpendicular to 
the vehicle traveling direction, une- ven, or waving are in the detection  
range.
●Strong wind is blowing
●When driving in inclement weather  such as fog, snow or a sandstorm
●When an object that cannot be detected is between the vehicle and a  
detected object
●If an object such as a vehicle, motor-
cycle, bicycle or pedestrian cuts in 
front of the vehicle or runs out from  the side of the vehicle
●If the orientation of a sensor has been changed due to a collision or other  
impact
●When equipment that may obstruct a 
sensor is installed, such as a towing 
eyelet, bumper protector (an addi- tional trim strip, et c.), bicycle carrier,or  
snow plow
●If the front of the vehicle is raised or 
lowered due to the carried load
●If the vehicle cannot be driven in a 
stable manner, such as when the 
vehicle has been in an accident or is  malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair  
kit is used
■Situations in which the system may 
operate even if there is no possibil-
ity of a collision 
In some situations, such as the follow- 
ing, the system may operate even 
though there is no possibility of a colli- sion.
